Physics. Hooke’s law states that the relationship between the stretch s of a spring and the weight w causing the stretch is linear. For a particular spring, a 5 -pound weight causes a stretch of 2 inches, while with no weight, the stretch of the spring is 0. (A) Find a linear equation that expresses s in terms of w . (B) What is the stretch for a weight of 20 pounds? (C) What weight will cause a stretch of 3.6 inches?

QUESTION 18 - 1 POINT
Jessie is playing a dice game and bets $9 on her first roll. If a 10, 7, or 4 is rolled, she wins $9. This happens with a probability of . If an 8 or 2 is rolled, she loses her $9. This has a probability of J. If any other number is rolled, she does not win or lose, and the game continues. Find the expected value for Jessie on her first roll.
Round to the nearest cent if necessary. Do not round until the final calculation.
